Rachel McAdams Long Straight Light Blonde Hairstyle with Blonde Highlights

Apply styling mousse to damp hair, using your palm as a measuring guide, and evenly distribute it along the hair shaft. Styling mousse will add hold and can help achieve better results.

Using the corner of your comb and standing in front of a mirror find the middle of your nose and then drag the comb straight up slowly until you reach your hairline and then continue back in a straight manner to achieve an even middle part. A middle part is a great way to make small, round face shapes appear longer and thinner.

A large radial brush is usually used on long straight hair types or to smooth out wavy or curly hair textures. When selecting a radial brush, always use one with a pure bristle as this will not tear or damage the hair.

To blow-dry under, start at the nape/back and place your brush under the section of hair close to the nape. With the dryer held up over the hair, pull the brush from the roots and continue to the mid length's, keeping the blow-dryer following over the top. Once you reach the ends, curve them under. Repeat this step until the section is completely dry.

To blow-dry the sides, take out a small section of hair from the front and clip the rest of the hair away. Next, place the brush under the section and then pull the brush and hair forward around your face (this curving motion creates body). Place the hair-dryer on top of the brush until you reach the ends and then turn the ends under. Repeat until dry.

Take a section of your hair no wider than the diameter of your brush. Place your brush under and at the roots of your section. Then with your blow-dryer above, drag the brush up through the mid-lengths and ends of the hair following with your blow-dryer and pulling the hair to the left. Repeat until your hair is completely dry.

Take a section of your hair no wider than the diameter of your brush. Place your brush under and at the roots of your section. Then with your blow-dryer above, drag the brush up through the mid-lengths and ends of the hair following with your blow-dryer and pulling the hair to the right. Repeat until your hair is completely dry.

Apply a very small amount of smoothing shine to the palms of your hands and then run it through the mid-lengths and ends of your hair. Be careful not to add any to the roots or a large amount to any section of the hair as smoothing shine can be very heavy on the hair, weighing it down and making it appear oily.

To finish, apply a minimal amount of hairspray from an arms length distance to the top, sides and back. Take care not to use too much or you will end up with a white, flaky residue which looks like dandruff.
